Ysleta del Sur Pueblo is a Puebloan Native American tribal entity in the Ysleta section of El Paso, Texas. Its members are Southern Tiwa people who had been displaced from Spanish New Mexico in 1680-1681 during the Pueblo Revolt against the Spaniards.
The people and language are called Tigua. They have maintained a tribal identity and lands in Texas. Spanish mostly replaced the indigenous language in the early 1900s, and today, English is increasingly gaining ground in the community. Today there are efforts to revive the indigenous language.
For almost 40 years the Pueblo has owned and operated tribal businesses that provide employment for its members and the El Paso community. These businesses include the Speaking Rock Entertainment Center, Big Bear Oil Co., Inc., and the Tigua Indian Cultural Center. The tribe employed approximately 500 individuals.
As part of the Indian termination policy followed by the federal government from the 1940s through the 1960s, the Tigua became the last tribe formally terminated.
